Bare Aluminum offers greater than 86% reflectance from near UV to mind IR. Aluminum will slowly oxidize, resulting in a significant loss of reflectance in the UV, and slight scattering throughout the spectrum. Therefore, it is best if aluminum has a protective dielectric overcoat. A protective overcoat will also substantially improve abrasion resistance, so that the coating is less susceptible to damage during cleaning and handling.
